Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.01904 |
| Opus 5.5 | $0.00026 | $0.00762 |
| Sonnet 5.5 | $0.00013 | $0.00381 |
| Haiku 4.5 | $0.00007 | $0.00190 |
Grade A, and why
api-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Constraints
- Apply
@rules/api/general.mdc— this skill is the focused review lens for that rule. - Apply
@rules/php/core-standards.mdc - Apply
@rules/security/backend.md— for the error-text and authorization-leak surface of API responses (401/403/404 wording, no internal-detail leak). - If the current project uses Laravel, also apply
@rules/laravel/architecture.mdcand@rules/laravel/laravel.mdc— validation belongs in FormRequest / Data Validator, controllers stay slim. - Apply
@rules/reports/general.mdc— when the findings are folded into the GitHub PR comment by a CR wrapper they stay in canonical English per the rule's Exception — technical CR findings on the GitHub PR; a non-technical mirror on a linked issue / JIRA ticket follows the language of the source assignment. HTTP verbs, status codes, header names, and code identifiers stay verbatim regardless of the surrounding prose language. - Output findings only — no praise, no summary of what was checked.
- Read-only skill — never modify code, never stage / commit / push, and never run any git write operation. Switching to the relevant branch and
git pullto read the latest diff are allowed; mutating the working tree or pushing is not.
Use when
- A PR or change set adds or modifies HTTP endpoints, routes, controllers, API Resources, request/response payloads, or status-code handling.
- Run as part of every code review via
@skills/code-review/SKILL.md(Specialized Reviews → Always run). - A consumer-facing API contract needs a design check before release.
Scope
Review only the API surface on the diff — never untouched endpoints. Detect the surface from any of: route definitions, controller/__invoke request handlers, API Resources / DTOs serialized into responses, FormRequests, response() / abort() / status-code calls, and Idempotency-Key handling. If the diff touches no API surface, return no findings.
Core Checks
Walk the diff against each pillar of @rules/api/general.mdc and raise one finding per match.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

api-review is a skill published in the GitHub repository pekral/cursor-rules (11 stars, last pushed 19d ago), licensed MIT. It adds 66 tokens to every session and 1,904 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
